LED is a highly efficient light-emitting diode device, it must operate at DC current environment to emit a steady bright light, illuminating the world. The driving power of the pros and cons will directly affect the quality of its light emission brightness and light. How to choose a good LED filament drive power is the key to cost-effective quality manufacturing LED filament lamp.

LED drive power can be converted into a specific power supply voltage and current to drive the LED light voltage converter, under normal circumstances: LED drive power input including high frequency alternating current (ie, electricity), low-voltage direct current, high-voltage direct current, low-voltage high frequency AC (eg electronic transformer output).
